More than 20 years ago, Congress passed a sanctions law that included a provision to help these Cuban exiles who are now U.S. citizens. The provision would allow them to sue in U.S. courts companies that operate using property that the exiles lost in the 1959 revolution.

If Trump activates the provision, it could reignite that opposition, complicating already rocky relations with Mexico, Canada, the European Union – and obviously Cuba – at a time when the U.S. needs their help to deal with the crisis in Venezuela.

As a scholar of U.S. relations with Latin America, especially Cuba, I’ve closely followed the Trump administration’s growing antagonism toward Havana. But activating Title III would represent a quantum leap in hostility.

Triggering new sanctions

The people who stand to benefit from activating this law are Cuba’s pre-revolutionary rich – what was once Cuba’s “One Percent.”

They arrived in the U.S. expecting Washington to quickly overthrow Fidel Castro and restore their power, property and privilege. Instead, the revolutionary government survived and by the 1990s was attracting foreign direct investment from Canada, Europe and Latin America.

Normally, U.S. courts have no jurisdiction over property owned by non-citizens that is nationalized by a foreign government. For U.S. courts to sit in judgment of another government’s actions towards its own citizens would be a challenge to that government’s sovereignty.

Since virtually all property in pre-revolutionary Cuba was privately held, the foreign companies operating there, including many that also do business in the U.S., fear being accused of profiting from confiscated property and getting caught up in Title III lawsuits.

Consequently, U.S. allies bitterly opposed the law as illegal U.S. interference in their commerce with Cuba.

The European Union filed a complaint against the U.S. with the World Trade Organization in 1996 and adopted a statute prohibiting EU members and their companies from complying with Title III. Mexico, Canada and the United Kingdom passed similar legislation.

In response, President Bill Clinton suspended Title III of the act for six months, which the law allowed. The suspension has to be renewed every six months. Since then, every president, Democrat and Republican, has renewed the suspension. Donald Trump has already renewed it three times.

But recently, there have been indications that the longtime practice of suspending Title III’s provisions may end soon.

The president has until the end of February to notify Congress if he decides to extend the suspension. Otherwise, Title III takes effect automatically.

Politics in command

According to The New Yorker magazine, Trump gave White House staff paltry guidance on Cuba policy at the beginning of his administration.

“Make Rubio happy,” he told them.

Sen. Marco Rubio, R-Fla., and Rep. Mario Díaz-Balart, R-Fla, are the principal advocates for Title III. They are Cuban-Americans who represent the oldest, most conservative and wealthiest segment of the Miami Cuban community. From their mansions in Miami, that elite still wields disproportionate influence over U.S. policy through these legislators.

Most Cuban-Americans will gain nothing from Title III. It exempts private residences from compensation. So, if an exile’s main asset was their home, they are out of luck.

Still, a 1996 State Department analysis estimated that Title III could flood U.S. federal courts with as many as 200,000 lawsuits, creating a legal morass that would take years to sort out.

In the meantime, most U.S. firms and some foreign ones would likely hesitate to enter into commercial relations with Cuba for fear of becoming litigation targets in the United States. That’s a major purpose of Title III – to stymie Cuba’s economic development.

Cuban American families have already voiced claims for the port of Havana and José Martí International Airport, putting cruise ship companies and airlines on notice that they could face potential legal jeopardy over their use of these properties.

If these companies pull out of the Cuban market, Americans would still have a right to travel to Cuba, but no way to get there.

If Title III reduces foreign investment in Cuba, it will damage Cuba’s already fragile economy, which in turn would hurt the standard of living of ordinary Cubans.

In retaliation, Havana might well stop buying agricultural goods from U.S. farmers. That’s a market of over $250 million annually that American farmers can ill afford to lose when exports are down due to Trump’s trade wars.

Trump believes he won Florida in 2016 because of the Cuban-American vote, and he thinks Rubio can deliver it again in 2020.

I think Trump is miscalculating.

The remnants of Cuba’s pre-revolutionary “One Percent” no longer represent the Cuban-American community as a whole. By decisive majorities, Cuban-Americans support free travel between the U.S. and Cuba, broader commercial ties and President Obama’s decision to normalize relations. Every year, they send $3 billion to family on the island, and hundreds of thousands of them travel there to visit.

Those Cuban-American voters may not want to inflict more economic pain on ordinary Cubans, including their friends and family. Come 2020, they may punish a president who does.
